Abstract We have performed abundance analysis of two slowly rotating, late A-type stars,
HD 32115 (HR 1613) and HD 37594 (HR 1940), based on obtained echelle spectra
covering the spectral range
4000-9850 Å. These spectra allowed us to identify an extensive line list for 31
chemical elements, the most complete to date for A-type stars. Two approaches to
abundance analysis were used, namely a "manual" (interactive) and a semi-automatic
procedure for comparison of synthetic and observed spectra and equivalent widths.
For some elements non-LTE (NLTE) calculations were carried out and the corresponding
corrections have been applied. The abundance pattern of HD 32115 was found to be very
close to the solar abundance pattern, and thus may be used as an abundance standard
for chemical composition studies in middle and late A stars. Further, its H
line profile shows no core-to-wing anomaly like that found for cool Ap stars and
therefore also may be used as a standard in comparative studies of the atmospheric
structures of cool, slowly rotating Ap stars. HD 37594 shows a metal deficiency
at the level of -0.3 dex for most elements and triangle-like cores of spectral lines.
This star most probably belongs to the
Sct group.
